Abstract: An improved, reusable, protective, reflective, weather resistant cover for a vehicle windshield-wiper-bay region and also for front-side windows and for the rear window region is disclosed. The cover is easy and fast to deploy, the operator is not required to reenter the vehicle for deployment and no cover element extends inside the vehicle. Permanent magnets and/or hook and loop strips are used to removably affix the cover. No permanently attached fastener elements are observable from within or without the closed vehicle. The cover effectively reflects the sun's rays reducing internal heating and material degradation and eases removal of frost, sleet or snow from covered regions.

Abstract: A suspended centrifuge apparatus has been improved by the addition of a restraint that closely maintains the original, static, vertical axis of a suspended centrifuge vessel during rotation. The restraint is preferably located to act on the lower half of the suspended vessel and preferably limits axial gyration to less than 5-degrees. A further improvement is a centrifuge bowl configuration which provides a protected surface to be acted on by a gyration restraint while partially eliminating centrifuge bowl capacity in a lower, central region subjected to inherently low centrifugal forces. An improved liquid separation process results from the use of the improved apparatus to better control the liquid discharge trajectory from the rotating centrifuge. Process control and safety are also improved.
